Three-phase ac motors have been the workhorse of industry since the earliest days of electrical engineering. They are reliable, efficient, cost-effective and need little or no maintenance. In addition, ac motors such as induction and reluctance motors need no electrical connection to the rotor, so can easily be made flameproof for use in hazardous environments such as in mines.
In order to provide proper speed control of an ac motor, it is necessary to supply the motor with a three phase supply of which both the voltage and the frequency can be varied. Such a supply will create a variable speed rotating field in the stator that will allow the rotor to rotate at the required speed with low slip. This ac motor drive can efficiently provide full torque from zero speed to full speed, can overspeed if necessary, and can, by changing phase rotation, easily provide bi-directional operation of the motor. A drive with these characteristics is known as a PWM (Pulse Width Modulated) motor drive.
Drives and motors are an integral part of industrial equipment from packaging,robotics, computer numerical control (CNC), machine tools, industrial pumps,and fans. Designing next-generation drive systems to lower operating costs requires complex control algorithms at very low latencies as well as a flexibleplatform to support changing needs and the ability to design multiple-axis systems.
Traditional drive systems based on ASICs, digital signal processors (DSPs), and microcontroller units lack the performance and flexibility to address these needs. Altera’s family of FPGAs provides a scalable platform that can be used to offload control algorithm elements in hardware. You may also integrate the whole drive system with industry-proven processor architectures while supporting multipletypes of encoders and industrial Ethernet protocols. This “drive on a chip” system reduces cost and simplifies development.
FPGA stands for field programmable gate array. FPGAs contain configurable logic blocks that can be connected through connection bars and modified for various applications. FPGAs have different features than ASICs and can be specified using HDL scripts similarly to ASICs. FPGAs provide advantages over ASICs such as shorter design time and lower costs.

Simulation results show the proposed FPGA design consuming 7mW of power which is reduced compared to non power gating approaches.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

8. Interconnection Framework
Granularity and interconnection structure
has caused a split in the industry
FPGA
– Fine grained
– Variable length
interconnect segments
– Timing in general is not
predictable; Timing
extracted after placement
and route
9. Interconnection Framework
CPLD
– Coarse grained
(SPLD like blocks)
– Programmable crossbar
interconnect structure
– Interconnect structure uses
continuous metal lines
– The switch matrix may or may not
be fully populated
– Timing predictable if fully
populated
– Architecture does not scale well
10. Field Programmability
Field programmability is achieved through
switches (Transistors controlled by memory
elements or fuses)
Switches control the following aspects
Interconnection among wire segments
Configuration of logic blocks
Distributed memory elements controlling the
switches and configuration of logic blocks are
together called “Configuration Memory”
11. Technology of Programmable
Elements
Vary from vendor to vendor. All share the
common property: Configurable in one of the two
positions – ‘ON’ or ‘OFF’
Can be classified into three categories:
SRAM based
Fuse based
EPROM/EEPROM/Flash based
Desired properties:
Minimum area consumption
Low on resistance; High off resistance
Low parasitic capacitance to the attached wire
Reliability in volume production
12. SRAM Programming

impedance state
But can be fused irreversibly into low impedance state
by applying high voltage

33. SRAM FPGA -- EEPROM
FPGA
An FPGA is similar to several other types of
devices which have been around for quite a
while, the difference being that an FPGA is
simply much more expandable and versatile.
The devices which FPGAs get compared to
most often are CPLDs (Complex
Programmable Logic Devices), which are
similar in function but typically have way less
logic gates inside them; Customizable CPU
design is much more feasible with an FPGA.
Once upon a time, CPLDs also had the
distinct advantage of retaining their
34. SRAM FPGA -- EEPROM
FPGA
when turned off; When FPGAs first came out,
they used simple SRAM to hold their
configuration, which of course would be lost
when the device lost power. Back then, the
FPGA had to be programmed from scratch
every time it was turned on, usually from a
separate serial ROM chip. But today, FPGAs
come in Flash, EPROM, and EEPROM
variants, which will retain configuration, and
which can also be re-programmed. (Fuse
and anti-fuse FPGAs also exist, which act
like PROMs in that they are one-time
35. SRAM FPGA -- EEPROM
FPGA
afterward.) Despite this, however, most
FPGAs still use SRAM for reasons of
simplicity (when you need to reprogram it, it's
easier to re-encode a small ROM chip than to
reprogram a large FPGA chip), so count on
having to use a separate boot ROM for the
FPGA.
Use of an FPGA is broadly divided into two
main stages: The first is "configuration
mode", the mode in which the FPGA is when
you first power it up. Configuration mode is,
as you may have guessed, where you

FPGA
this is when you load your code into it,
dictating how the pins behave. Once
configuration is complete, the FPGA
goes into "user mode", its main mode of
operation, where the programmed
circuit actually starts functioning.
37. Product – FPGA vs ASIC
Comparison:
FPGA benefits vs ASICs:
- Design time: 9 month design cycle vs 2-3 years
- Cost: No $3-5 M upfront (NRE) design cost.
No $100-500K mask-set cost
- Volume: High initial ASIC cost recovered only in very high volume products
Due to Moore’s law, many ASIC market requirements now met by FPGAs
- Eg. Virtex II Pro has 4 processors, 10 Mb memory, IO
Resulting Market Shift:
Dramatic decline in number of ASIC design starts:
- 11,000 in ’97
- 1,500 in ’02
FPGAs as a % of Logic market:
- Increase from 10 to 22% in past 3-4 years
FPGAs (or programmable logic) is the fastest growing segment of the
semiconductor industry!!
